Decoding Your Blood Sugar Levels: A Guide to mg/dL and mmol/L
Understanding your blood sugar levels is crucial for maintaining good health, especially if you have diabetes or are at risk of developing it. Blood sugar levels are typically measured in two different units: mg/dL (milligrams per deciliter) and mmol/L (millimoles per liter). This guide will help you decode these units, understand healthy ranges, and learn how to manage your blood sugar effectively.
What Are mg/dL and mmol/L?
- mg/dL (milligrams per deciliter): This unit measures the concentration of glucose in your blood, expressed as milligrams of glucose per deciliter of blood. It's commonly used in the United States.
- mmol/L (millimoles per liter): This unit also measures glucose concentration but uses millimoles per liter. It is the standard unit in many countries, including Canada and the UK.
Both mg/dL and mmol/L provide the same essential information – the amount of glucose present in your blood at a specific time. The difference lies solely in the units of measurement used.

Understanding Blood Sugar Level Ranges
Healthy blood sugar ranges vary depending on whether you’re testing before a meal (fasting) or after a meal (postprandial). Here’s a general guideline, but always consult with your healthcare provider for personalized recommendations.

| Category | Fasting (mg/dL) | Fasting (mmol/L) | 2-Hour Postprandial (mg/dL) | 2-Hour Postprandial (mmol/L) |
|---|---|---|---|---|
| Normal | Less than 100 | Less than 5.6 | Less than 140 | Less than 7.8 |
| Prediabetes | 100-125 | 5.6-6.9 | 140-199 | 7.8-11.0 |
| Diabetes | 126 or higher | 7.0 or higher | 200 or higher | 11.1 or higher |
- Fasting Blood Sugar: Measured after at least eight hours of not eating.
- Postprandial Blood Sugar: Measured two hours after starting a meal.
Important Considerations: These are general guidelines and may vary slightly depending on individual circumstances, age, and health conditions. Pregnant women, for instance, have different target ranges.
Converting Between mg/dL and mmol/L
To convert between mg/dL and mmol/L, you can use the following formulas:
- mg/dL to mmol/L: Divide the mg/dL value by 18.
- mmol/L to mg/dL: Multiply the mmol/L value by 18.
For example, a blood sugar level of 90 mg/dL is equivalent to 5.0 mmol/L (90 / 18 = 5.0). Similarly, 7.0 mmol/L is equivalent to 126 mg/dL (7.0 * 18 = 126).
Monitoring Your Blood Sugar Levels
Regular blood sugar monitoring is a cornerstone of diabetes management and can also be beneficial for those looking to maintain healthy glucose levels. There are several ways to monitor your blood sugar:

- Glucometer: A portable device that measures blood glucose from a small blood sample, usually obtained by pricking your finger.
- Continuous Glucose Monitor (CGM): A device that continuously tracks blood glucose levels through a small sensor inserted under the skin. CGMs provide real-time data and trends, which can be incredibly helpful for fine-tuning your diabetes management plan.
Factors Affecting Blood Sugar Levels
Many factors can influence your blood sugar levels. Understanding these factors can help you make informed choices to maintain healthy glucose levels:
- Diet: The type and amount of carbohydrates you consume significantly impact blood sugar levels.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity and using glucose for energy.
- Medications: Certain medications, including insulin and oral diabetes drugs, can lower blood sugar. Other medications, such as corticosteroids, can raise it.
- Stress: Stress hormones can increase blood sugar levels.
- Illness: Being sick can also elevate blood sugar.
- Dehydration: Insufficient water intake can lead to higher blood sugar concentrations.
- Sleep: Lack of sleep or poor sleep quality can affect insulin sensitivity and blood sugar control.
- Time of Day: Hormonal fluctuations throughout the day can affect blood sugar levels. This phenomenon is often referred to as the dawn phenomenon.
Managing Blood Sugar Levels Effectively
Effective blood sugar management involves a combination of lifestyle changes and medical interventions, tailored to your individual needs.
- Healthy Diet:
- Focus on whole, unprocessed foods.
- Control carbohydrate intake, choosing complex carbs over simple sugars.
- Include plenty of fiber-rich foods, such as vegetables, fruits, and whole grains.
- Eat regular, balanced meals.
- Regular Exercise:
- Aim for at least 150 minutes of moderate-intensity aerobic exercise per week.
- Include strength training exercises at least twice a week.
- Consult with your doctor or a certified trainer to develop a safe and effective exercise plan.
- Medication Adherence:
- Take medications as prescribed by your healthcare provider.
- Understand the potential side effects and interactions of your medications.
- Communicate any concerns or questions to your doctor or pharmacist.
- Stress Management:
- Practice relaxation techniques, such as meditation, yoga, or deep breathing.
- Engage in hobbies and activities that you enjoy.
- Seek support from friends, family, or a therapist.
- Regular Monitoring:
- Check your blood sugar levels regularly, as directed by your healthcare provider.
- Keep a log of your blood sugar readings, meals, activities, and medications.
- Share this information with your doctor to help optimize your treatment plan.
- Adequate Hydration:
- Drink plenty of water throughout the day.
- Avoid sugary drinks, such as sodas and juices.
- Sufficient Sleep:
- Aim for 7-9 hours of quality sleep each night.
- Establish a regular sleep schedule.
- Create a relaxing bedtime routine.
When to Seek Medical Attention
It’s essential to know when to seek medical attention for blood sugar levels. Contact your doctor immediately if you experience any of the following:
- Severely High Blood Sugar (Hyperglycemia): Blood sugar levels above 250 mg/dL (13.9 mmol/L) accompanied by symptoms such as increased thirst, frequent urination, blurred vision, or confusion.
- Severely Low Blood Sugar (Hypoglycemia): Blood sugar levels below 70 mg/dL (3.9 mmol/L) accompanied by symptoms such as shakiness, sweating, dizziness, hunger, or confusion.
- Frequent High or Low Blood Sugar Episodes: If you are experiencing frequent fluctuations in your blood sugar levels, despite following your management plan.
- Signs of Diabetic Ketoacidosis (DKA): DKA is a serious complication of diabetes that can occur when blood sugar levels are very high. Symptoms include nausea, vomiting, abdominal pain, rapid breathing, and fruity-smelling breath.
- Loss of Consciousness: If you lose consciousness due to high or low blood sugar levels, seek immediate medical assistance.
Conclusion
Understanding your blood sugar levels in both mg/dL and mmol/L is vital for proactive health management. By regularly monitoring your blood sugar, adopting a healthy lifestyle, and working closely with your healthcare provider, you can effectively manage your blood sugar levels and reduce your risk of diabetes-related complications. Remember, personalized guidance from a healthcare professional is always the best approach for managing your individual health needs.
